The Petzl EXO is a unique device designed specifically for firefighters. It provides a firefighter with an alternate (last resort) means of escape if there is no other way out from an upper floor during an emergency.

The Petzl EXO comes with an anchor hook, 50-feet of 7.5mm Technora cut and heat resistant rope, the EXO auto-locking descent control device, an attachment carabiner with captive eye and a carry bag. The system also requires a Class-2 harness for use (the preferred harness is the Gemtor Model #541NYCL).

Training IS required by Petzl before the system can be placed into service. This system is not a typical rope/belay system. There are characteristics of its function and operation that require a bit more care and attention.

The rope is a bit different, and I've no idea of RRP, but if you're a climber then a screwgate, 15m of 8mm, a Grigri and an old harness gets you 95% of the way. Add an aid hook and you've got basically the full kit. In an emergency a bolted in desk leg could work as an anchor, or put something across a doorway or window Die Hard style.

Substitute a traditional descender for the Grigri and you're going to be even cheaper. Sub a retired rope and harness and you could probably have a kit under your desk for about $0.

But that's just me being a tight-arse. I'd look at where you're likely to be, and where you could stash stuff for a foreseeable emergency.

Miguel, why am I reminded of a fire brigade captain who once sat up into the early hours of the morning in his kitchen playing poker with his fire crew while waiting for his business premises to catch fire?
